Neutrophil activity

A study by Iorwerth et al (The Knee, 2003) indicates that the use of autologous filtered blood alters the activity of PMN, thereby reducing the incidence of post-operative infections (A Iorwerth et al, 2003, see ref below).

Reduced exposure to allogeneic blood

In the study by Moonen et al (Transfusion, 2007) it was concluded that post-operative transfusion of filtered autologous whole blood is effective for decreasing allogeneic blood transfusion after total hip and knee arthoplasty.
